At dawn, Feyre marches with the allied army through the mortal lands and sees Hybern’s destruction firsthand. Her old village has been burned, her father’s estate is half-ruined, Elain’s garden is destroyed, and the attack feels deliberately personal. Cassian notes that Hybern left some of the estate standing because the king is hurrying to secure the most advantageous battlefield, so the army presses on despite the strain of coordinating many forces.

During a midday stop, Feyre and Nesta change into Illyrian leathers, and Nesta takes a knife despite her lack of training. Elain is uncomfortable with the leathers and refuses Cassian’s blade, but Azriel gently offers her Truth-Teller instead, saying it has never failed him. Feyre notices the significance of Azriel entrusting the knife to Elain, while Rhys lightens the mood before gathering their court together for a final speech about gratitude, chosen family, and facing death only when it comes for them.

When they reach the sea-scented plain Hybern has chosen, the danger becomes plain. Hybern holds the high ground and vastly outnumbers them, making a direct assault costly and giving the king every advantage. Cassian estimates that if the battle turns badly, they may only have a few hours before shields fail and Hybern brings the Cauldron fully to bear, while Azriel warns Feyre that strong wards may force her to reach it on foot once the battle grows chaotic.

As the armies form up, the opening clash is magical rather than physical, with both sides trying to break each other’s shields. Rhys conserves his power for the crucial moment, and Feyre realizes Hybern would detect him if he tried to sneak across the field. While the shields strain, Feyre tells Rhys she never gave him a mating present and then reveals the bargain she secretly made after surviving the Ouroboros: she has brought the Bone Carver, freed in a Fae body, and Bryaxis to the battlefield.

Feyre explains that the Ouroboros showed her herself, including everything cruel, cowardly, proud, and wounded within her, and that she overcame it by accepting and loving all of it. Then Rhys reveals he has made a bargain of his own: Helion secured the Weaver’s aid in exchange for breaking her containment spell. With the Bone Carver, Bryaxis, and the Weaver now assembled together, the three ancient horrors launch themselves at Hybern’s army, dramatically changing the opening of the final battle.
